Modern features, classic Onkyo power

Home theater receivers perform lots of functions, but none more important than providing your speakers with plenty of clean power. Onkyo has never lost sight of this. That's why the foundation of their TX-NR525 home theater receiver is a large power supply. So whether you're listening to music in stereo or movies in surround sound, this receiver will provide plenty of juice so your speakers can deliver the goods. Connect up to five speakers plus two subwoofers and discover what immersive surround sound can do for movie and TV soundtracks. With six HDMI inputs, there's more than enough room for all your digital sources, from Blu-ray players to gaming consoles and streaming media boxes. Plus, the front-panel USB port is perfect for an iPod®, iPhone®, or iPad®, which you can control with the receiver's remote.

Endless options for digital music

If you want to really expand this receiver's features, then be sure to connect it to your home network. That opens up a broad selection of digital music. Stream tunes from services like Spotify®, Pandora®, and SiriusXM®. Or discover cool radio stations from around the world with TuneIn Internet radio.

Onkyo TX-NR525

Great receiver so far. Had a friend of mine, far more electrical savvy than I, help to get it set up but even with that I think if I had to do it myself, that the Crutchfield helpers would have been able to get me through it. It has made everything I have in the entertainment center operational.

Easy set up great sound

My last Onkyo needed to be replace after 8 years. I was skeptical about this unit as it was about half the cost of my last one. What a shock to have it blow my old Onkyo out of the water. My sound is much crisper, clearer, and my base hits harder. So far so good.

Pros:Easy set up.

Cons:It is hard to see the type on the unit over the black. If changing sources at the unit, I have to get very close to read it.

Easy to Set Up, great to use

This receiver was recommended by Crutchfield to replace an older Onkyo model that lacked HDMI inputs. Set up was incredibly easy including using the automatic speaker adjustment feature. The receiver seamlessly changes between components and allows for numerous different inputs. I am currently using Apple TV, an Blue-ray player, an a SiriusXM receiver and have room for several more components if i desire. Definitely a good value.

Onkyo AV Receiver

I had, 30 years ago, owned an Onkyo receiver, before purchasing my Denon (which served me very well). The Denon was starting to develop some glitches and I really wanted some updated connections and other options, so I started looking. The TX-NR525 had pretty much everything I was searching for. Plenty of HDMI inputs (1 output), lots of other inputs (both digital and analog) and a reasonably easy set up and remote. BE CAREFUL OF THE HEIGHT of this unit . . it is pretty tall and I had to make some cabinet adjustments to fit the unit. Otherwise it is outstanding and the sound quality, switches, remote . . everything works and sounds excellent. I was moving from a conventional analog receiver, which was quite old, to this far more complex receiver. I thought the set up (if you pay attention to the instructions) was not horrible. The only thing which I wanted, but had to do an end run to get, was a phono preamp. I could not find a reasonably priced receiver with a phono preamp, so I bought a separate, compact, outboard preamp which solved my problem. The only complaint I had was that the full manual for the unit comes on a CD. I appreciate having the pdf, but during the initial set up, really would have preferred the book.

Pros:Flexibility. Inputs, Controls, Remote, Appearance

Cons:Lack of hard copy of manual booklet (comes on a CD), height of unit, no phono preamp

Receiver with all the features

Love this receiver. We upgraded from a dinosaur, but this is a great one for the cost. All of our equipment is run from our basement up to our living room so on screen display was a must (which most come with now anyway). The wi-fi is nice for music not sure if video really works... haven't had time to fully test.

Pros:Wi-Fi Capability, App available,

Cons:Doesn't play .mp4 files from wi-fi, could be as designed or an issue on my end. Phone app not 100%

Onkyo-TX NR525

A good receiver/amp worth what I paid and has some good features, WI-FI and wired network but is not as good as my Sony STR-DG810 6.1 channel or my Sony STR-DG510 both purchased in 2007 which also have HDMI inputs and a sound that out performs the Onkyo 525 .

Love this receiver!

Love the quality of the sound out of this unit, but the on screen graphics are crude to say the least.

Pros:Great sound quality and the set up is easy. Built in net streaming.

Cons:The on screen graphics are very crude. I really expected more from Onkyo. The Onkyo app was a little better. I found an app in the Apple App Store that was much better. It is oRemote and it offers a much better interface than either the on screen graphics or the Onkyo app.

Onkyo Receiver 525

My onkyo 525 replaced Onkyo 515 in service less than one year. Several years ago I replaced my upper end Onkyo receiver that had provided me with over seven years of trouble free service with a low end Denon with HDMI connections. It lasted only a few months to be replaced by the Onkyo 515 now replaced with this second Onkyo 525. (The first was sent to Onkyo repair shop for a five week est fix to replace something to do with the HDMI controller). Could not do without a receiver for this time so purchased the 525. If is was not for the OUTSTANDING Crutchfield tech support, I would be completely lost.......I would not think about buying from anyone else!! Some might think I am crazy to continue with Onkyo products since I have had so many problems in the past year. Primary reason is the speaker connections on the rear are on the left where my cables can easily connect. The Denon are on the right and gave me trouble as I do not have a lot of slack int the cables when installed over 12 years ago. The newest 525 has been working good with no issues since installation a week ago. Today receivers and probably most electronics do not come with a printed Manuel but you get a disc or go online for a download. If I had to depend on the Manuel for the setup, I would still be reading. What a mess. With all of today's options, it was very gratifying to be able to call Crutchfield , talk to a live English speaking southern gentleman to walk me through the various settings.

Pros:Crutchfield......number of HDMI connections, and pass through option

great sound

Very good value from Crutchfield and fast shipping. The receiver was up and running in no time. The manual is a must read as the receiver is packed with features. I still have not gotten the wireless feature to work, but I have not had the time to read through the manual on this feature. However, I did get the receiver to join my network.

Pros:Powerful, clean sound. Does not seen to get hot.

Cons:A little complicated. As I stated read the manual. I tend to just jump in and wing it.

Firmware upgrade needed

iPhone app did not work initially. Had to delete the app, download the latest version and do a firmware upgrade. This took about an hour to resolve but tech was very diligent throughout. Works fine now. Very happy with purchase.

Pros:App, streaming music, connections for hdmi, component video, zone 2, remote is easy to use, able to set up cable remote to control receiver

Cons:Taller than previous amp, seems to run hot so I gave it enough open room

Great Receiver

Amazingly easy to set up and has the Onkyo reputation for quality. Price was excellent and delivery was quick as it always is with Crutchfield. This is my third Onkyo receiver from Crutchfield in the past 15 years and I've bought a number of car units from them in the past. When I had questions, they were there to help. Why go anywhere else?

Pros:Great sound and easy to set up.

Cons:Wireless is a problem because it won't accept my password, but I don't need that feature anyway.

Good Reciever, awesome service

Just got this as a replacement for TX-NR515. Receiver is good - does everything it says well. My real review is about Crutchfield service - they are awesome. Don't buy anywhere else. I originally bought a TX-NR515 about 2 months ago and had a problem out of the box. Crutchfield was great and got me a new receiver instantly. After 63 days the receiver died for no reason. I thought I would have an issue but Crutchfield is first class company and took care of me by upgrading me for free to this receiver. Came in two days and has been great. Love Crutchfield!

WRAT (Wide Range Amplifier Technology): WRAT is
based around a low negative-feedback circuit topology that works to
reduce signal noise and distortion across the frequency range. A
"closed ground-loop circuit" design is employed, in which each
circuit has a separate link to the power supply. This helps to
cancel individual circuit noise and keep the ground potential free
of distortion. High Instantaneous Current Capability (HICC) enables
WRAT amplifiers to immediately cancel the speakers' reflex energy
and instantaneously send out the next signal. The same high current
better manages speaker impedance fluctuations, which can negatively
affect performance.

H.C.P.S. (High Current Power Supply): Under the
anti-resonant cover of any Onkyo receiver, you'll instantly notice
the High Current Power Supply (H.C.P.S.) transformer. With its huge,
isolated power supply design and high-capacity filter capacitors, it
delivers the large amounts of power necessary for reproducing the
wide dynamics of movie soundtracks and the detail and clarity of
your music.

Optimum Gain Volume Circuitry: Optimum Gain
Volume Circuitry adjusts the gain so that less than half the amount
of attenuation is needed, ensuring the signal never comes close to
the noise floor. This protects the signal against noise, resulting
in a dramatically clearer sound.

Note: Dolby Digital and DTS listening modes can
only be selected if your audio source is connected to the AV
receiver via a digital audio connection (HDMI, optical or coaxial).
Even though the AV receiver will decode 7.1channel surround sound
(via HDMI), it will only output 5.1ch surround, because it lacks
Surround Back channel speaker outputs.

Onkyo Original DSP Modes: Onkyo's Original DSP
Modes, combined with Dolby Digital/DTS/Dolby Pro Logic processing,
produce more realistic, powerful sound effects for your movie and music
sound tracks based on the type of content and your home theater setup.
You can choose from the following:

All Ch Stereo: Stereo sound from all speakers.
Ideal for background music.

Full Mono: All speakers output the same sound
in mono.

Theater-Dimensional (T-D): Theater-Dimensional
circuitry takes the complexity out of conventional surround-sound
setups and lets you experience the excitement of surround sound from
as few as two ordinary speakers. Theater-Dimensional's unique
multi-speaker modes let you place up to five speakers conveniently
by the TV, for the most realistic virtual-surround sound possible.

Audyssey MultEQ Automatic Speaker Setup:
With the supplied speaker setup microphone, Audyssey MultEQ
determines the number of speakers connected, their optimum crossover
frequencies, and their distances from the primary listening
position, then adjusts each automatically. The room's acoustical
properties are then measured and corrected over the listening area
in both the frequency and time domain. There is a threaded insert on
the bottom of the microphone so it can be mounted on a tripod for
accurate listening position placement. Up to 6 listening position
measurements are taken to optimize the surround effect for a broad
area. If you prefer you can also setup your speaker system manually.

Audyssey Dynamic EQ: Audyssey Dynamic EQ solves
the problem of deteriorating sound quality as volume is decreased by
taking into account human perception and room acoustics. Dynamic EQ
selects the best possible frequency response and surround levels
moment-by-moment as volume is changed. The result is bass response,
tonal balance and surround impression that remain constant despite
changes in volume. Audyssey Dynamic EQ combines information from
incoming source levels with actual output sound levels in the room,
a prerequisite for delivering a loudness correction solution.
Audyssey Dynamic EQ works in tandem with Audyssey 2EQ to provide
well-balanced sound for every listener at any volume level.

Audyssey Dynamic Volume: Audyssey Dynamic
Volume solves the problem of large variations in volume level
between television programs, commercials, and between the soft and
loud passages of movies. Dynamic Volume looks at the preferred
volume setting by t he user and then monitors how the volume of
program material is being perceived by listeners in real time to
decide whether an adjustment is needed. Whenever necessary, Dynamic
Volume makes the necessary rapid or gradual adjustments to maintain
the desired playback volume level while optimizing the dynamic
range. Audyssey Dynamic EQ is integrated in Dynamic Volume so that
as the playback volume is adjusted automatically, the perceived bass
response, tonal balance, surround impression, and dialog clarity
remain the same whether watching movies, flipping between television
channels, or changing from stereo to surround sound content.

Dolby Pro Logic II Music Settings: While
listening in the Dolby Pro Logic II Music format, there are three
further enhancements you can adjust; Panorama: (broadens the front
stereo image to the surround speakers to provide a wraparound
effect), Dimension (allows you to move the sound field forward or
backward), and Center Width (allows you to adjust the width of the
center channel).

Center Image: In the Neo:6 Music mode, the
Center Image feature adjusts the output of the left and right
channels relative to the center channel, allowing you to make the
center channel more or less dominant as needed. This improves the
image of the center channel, especially when the listener is
off-center. Adjustment varies from 5 (nothing subtracted from the
L/R channels) to 0 (L/R channel output is cut in half).

Screen Centered Dialogue: By using the front
high speakers, this function moves the center image of the dialogue
upwards, so that the image of dialogue is fixed to the display
height.

Listening Angle: While listening in the Theater
Dimensional mode you can adjust the listening angle to either Wide
(if listening angle is 40°) or Narrow (if listening angle is 20°).

CinemaFilter: Using the CinemaFilter you soften
overly bright movie soundtracks. Movie soundtracks are typically
mixed for a large theater (relative to your home theater) with lots
of soft seats and thick curtains on the walls. Home theater settings
often lack these high frequency absorbing wall treatments, making
the soundtrack sound too bright. CinemaFilter accounts for this and
for many movies sounds more natural at home.

Music Optimizer: The Music Optimizer function
enhances the sound quality of compressed music files. The Music
Optimizer function only works with PCM digital audio input signals
with a sampling rate below 48kHz and analog input signals.

Late Night Feature: The Late Night feature
limits the dynamic range of Dolby Digital recordings. Limiting the
dynamic range makes it easier to find a volume that ensures the
quiet sounds are not too quiet and the loud sounds are not too loud
for night time listening. This allows you to comfortably listen to
without the need to constantly adjust the volume to keep from waking
family/neighbors. The choices are: Off, Low, and High. This feature
only works with Dolby Digital Encoded software and the depth of the
feature will vary based on the individual software package.

Assignable Digital Inputs: The Onkyo receiver
is equipped with one optical digital input and two coaxial digital
inputs. All three digital inputs are assignable. You can choose auto
decoding , PCM, or DTS for the digital audio inputs. Auto will
decode the signal in its original form (Dolby Digital, DTS, PCM,
etc), PCM decodes the signal to 2-channel, while DTS decodes only
DTS formatted sources.

Binding-Post Speaker Terminals: There are
color-coded binding-post terminals for the following speaker
connections; Front, Center, and Surround. The binding post terminals
will accept bare-wire, pin-connectors, and banana plugs
(single/dual).

Dual Subwoofer Outputs: The receiver is fitted with two
subwoofer outputs to connect dual powered subs for extra bass. Use
6- to 16-ohm speakers.

Headphones: When headphones are plugged into
the full-size 1/4" jack on the front panel, all the speakers are
automatically muted. When you connect an iPod or iPhone to the USB
port on this receiver, no sound will be output from the headphone
jack.

Video Features

HDMI (v1.4): The TX-NR525 has six assignable HDMI
v1.4 inputs and one HDMI v1.4 output for connecting Blu-ray/DVD players,
Satellite/Cable boxes, Game Consoles, and other video components to your
TV. The HDMI jacks can accept and switch 480i, 480p, 720p, 1080i, 1080p,
and 4K video signals to a HDTV. The HDMI jacks will also support
uncompressed standard or high definition digital video along with the
following audio signals; 2-channel linear PCM, Multichannel linear PCM
(up to 7.1ch), and Bitstream (Dolby Digital/DTS, etc.). In addition, the
HDMI jacks are 3D, ARC, HDMI-CEC, Deep/x.v.Color, and Auto Lip-Sync
compatible.

4K Pass Through: 4K Pass Through allows the
Onkyo TX-NR525 to receive ultra high-definition resolution video and
pass the video signal to a 4K compatible TV or display monitor. This
ensures compatibility with the latest super high resolution video
formats.

Deep/x.v.Color Support: The Onkyo receiver
supports Deep Color and x.v.Color content, which can display a
larger color range than standard-definition schemes. The result is a
more lifelike, vibrant picture.

ARC (Audio Return Channel): This feature allows
audio to be sent from your compatible HDTV to your receiver through
the same HDMI cable already being used to send audio and video to
your HDTV. This eliminates the need for extra cables connected to
your television. The receiver's main HDMI monitor output supports
the ARC function, while the sub HDMI monitor output does not.

Auto Lip-Sync: The Lip-Sync function can
automatically synchronize HDMI audio and video that has gotten out
of sync due to the complex digital video processing being performed
by your HDMI-compatible TV. With HDMI Lip-Sync, the audio delay
required to synchronize the audio and video is calculated and
applied automatically by the AV receiver.

HDMI Through: When enabling the HDMI Through
function, regardless of whether the AV receiver is "on" or in "standby"
both audio and video streams from an HDMI input will be output to your
television, via the receiver HDMI monitor output. You can select between
3 HDMI Through functions modes.

Last: The HDMI Through function is activated on
the input source selected at the time of setting the AV receiver to
the "standby" mode.

InstaPrevue: InstaPrevue technology provides a live
video thumbnail of the available content on your devices connected to
the receiver via HDMI. As a result, you can preview audio/video streams
coming from up to 5 HDMI inputs previously assigned to input selectors
on your HDMI connected TV. Even with multiple components connected to
receiver through HDMI, you can easily switch between inputs as their
previews are displayed on a single screen on your television. You can
even use the InstaPrevue feature for Picture-in-Picture. You can specify
the number of preview thumbnails, as well as their positioning
on-screen.

Note: If no video signal are present, the
thumbnails will be filled in black. With 3D video signals, the image
may not be properly rendered on the preview thumbnails of
InstaPrevue.

Analog Video Inputs: The receiver features five
composite video inputs (4 rear/1 front) and one composite video monitor
output. There are two component video inputs and one component video
output. You must connect the receiver to your TV via composite and/or
component video to view incoming video from the receiver's
composite/component inputs. There is no analog video conversion.

Front-Panel AV Input: The Onkyo TX-NR525 is equipped
with a front-panel audio/video input which consists of a composite video
terminal and stereo audio RCA jacks.

Picture Adjust: Using the Picture Adjust feature,
you can adjust the picture quality and reduce any noise appearing on
your TV screen.

A/V Sync Control: Occasionally, you may need to
manually adjust the audio/video signals that are not properly
synchronized manually. Typically when using a progressive scanning DVD
player. You can correct this by delaying the audio; options are 0 (no
delay) to 400 milliseconds, in 10 millisecond steps.

Note: Apple iPod/iPhone software updates may change
functionality results. If you download a newer software version, you
may need to reset the unit and your iPod/iPhone to regain
functionality. If this doesn't work, you may need to wait until a
newer software update is available.

Convenience Features

On-Screen Display (via HDMI): The Onkyo AV receiver
offers an on-screen setup menu through its HDMI output. The on-screen
display offers multiple language text, such as - English, French,
Spanish, German, and Italian. If your TV is connected to the composite
video or component video monitor output, you will need to use the AV
receiver's front-panel display when changing settings.

Zone 2 Line Out: By using the Zone 2 line-level
outputs on the TX-NR525, you can connect an external receiver or
integrated amplifier in a second room, allowing you to listen to 5.1ch
surround in the main room and 2ch stereo of a different audio source in
another room of your home. The volume of Zone 2 is controlled by your
optional integrated amp.

Compatible Zone Sources: Only Tuner, analog, USB, and
Network audio sources can be sent to Zone 2. You cannot select different
AM/FM radio stations or listen to USB and Network content in separate Zones
at the same time.
To playback Bluetooth audio in Zone 2, you must also have Bluetooth selected
as your source in the main zone.

Name Edit: You can enter a custom name for each
individual input selector and radio preset for easy identification. When
entered, the custom name will appear on the display. This function
cannot be used for the Network and USB input selectors.

Display Dimmer + Screen Saver: The display
brightness has three settings; Dim, Dimmer, and Normal. If there is no
video signal on the current input source and no operation for a specific
time, a screen saver automatically comes on. You can set the time
(3min/5min/10min/off) until the screen saver activates itself. Once
active, the screen saver will go off and the screen will return to its
previous state if the AV receiver is operated in any way.

Auto & Hybrid Standby: The AV receiver will
automatically go into Standby mode, if there is no operation for 30
minutes with no audio/video signal input. The Onkyo TX-NR525 features
"Hybrid Standby" mode to save energy and provide greater levels of
convenience. Hybrid Standby Mode provides "HDMI through" functionality
and maintains a local network connection while the receiver is
essentially powered down. This allows the user to watch TV without
turning the whole surround system on. Furthermore, when on Hybrid
Standby, the home theater may be powered up from "cold" using the Remote
Apps for iPod touch/iPhone and Android.

Sleep Timer: From the remote, you can set the unit
to automatically turn off after as much as 90 minutes or as little as 10
minutes; choices are presented in 10 minute increments.

Optional Bluetooth Adapter (sold separately): The
Onkyo UBT-1 Bluetooth USB Adapter
(580UBT1,
sold separately) lets you wirelessly stream music from your
Bluetooth-enabled smartphone, portable audio player, tablet, laptop, or
PC to the Onkyo A/V receiver. The Onkyo UBT-1 is fitted with a male USB
(type-A) connector which plugs into the Onkyo receiver's USB (type-A)
port. The Onkyo UBT-1 is Bluetooth version 3.0 certified and lets you
wirelessly stream music from many Bluetooth-enabled devices supporting
A2DP (Advanced Audio Distribution Profile). The Onkyo UBT-1 is equipped
with apt-X, an audio coding technology that works within Bluetooth to
wirelessly deliver CD-quality audio from your Bluetooth-enabled device
to the Onkyo A/V receiver.

Note: Due to the differences in Bluetooth
technology, some Bluetooth enabled devices may be incompatible,
function improperly, or may not support all features when used with
the Onkyo UBT-1.

Remote Control

Multi-brand Remote: The receiver comes with an IR
remote control for wireless operation of this receiver and other
HDMI-connected sources (via HDMI CEC). In addition to the receiver, the
remote can be programmed to control popular brands of TVs, Blu-ray
players, DVD players/recorders, DVRs, VCRs, etc.

The AV receiver will enter Standby mode when the power of the TV
is turned to Standby.

You can set on the menu screen of the TV to either output the
audio from the speakers connected to the AV receiver, or from the
speakers of the TV.

It is possible to output the audio/video from the antenna or
from the input jack of the TV from the speakers connected to the AV
receiver.

Input to the AV receiver can be selected with the remote
controller of the TV.

Operations such as volume adjustment or similar for the AV
receiver can be performed from the remote controller of the TV.

RI Remote Control Jack: The 1/8" RI remote control
jack allows you to connect this receiver to other compatible Onkyo
components.

Onkyo Remote App (for Apple iOS & Android): The Onkyo Remote
App (from
iTunes Apps &
Google Play) allows you to operate the Onkyo AV receiver from your
Apple iOS (4.3+) or Android (2.1+) device, using your home's wireless
network. The Onkyo Remote App lets you you access Internet Radio
stations, AM/FM stations, DLNA content, and Input sources right from
your mobile device. Content information will be displayed on the

modes, and speaker volume from your compatible Apple iOS or Android
device. The Onkyo Remote App even allows you to wirelessly
